David came to the ACA from a diverse background in science, the humanities and industry. After first completing an M.Phil degree with the ACA in 2010, he went on to study early microbial ecosystems preserved in rocks of the Pilbara region, Western Australia, during a PhD supervised by ACA Foundation Director Malcolm Walter.
David’s research at the ACA included several seasons of geological fieldwork in the Pilbara supported by the Geological Survey of Western Australia, as well as an opportunity to study Shark Bay and other modern analogues for ancient ecosystems in both field and laboratory settings.
David continues his research as a Caltech Postdoctoral Scholar at the NASA Jet Propulsion Laboratory in Pasadena, California. His current research interests include biosignatures in Archean (4 to 2.5 billion-year-old) rocks and Martian geology. “My time at the ACA was the perfect balance of adventure, science and career development”, he says.
